To all whom it may concern:

Be it known that I, IIENRY L. Kennels, a

citizen of the United States, residing at Lundys- Lane in the county ofEric and State of Pennsylvania, have inventedcertain new and usefuiImprovements in A0- tuating Mechanism for Station-Indicators; and I dohereby declare the following to pea full, clear, and exact descriptionoft-he nvention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being bad to theaccompanying drawings, and to the letters of reference marked thereon,forming part of this specification;

This invention relates to station indicator operating mechanism, and hasfor its object the construction and installment on cars of mechanism forautomatically operatingsta- 20. they move along the roadway.

I The features of my invention are hereinafter 'fully set forth'andexplained and diagrammatically illustrated in the accompanying drawingsin which:

depressed as the flanges tion indicator mechanism in such cars asFigure 1. shows diagramn'iatically a mechanism embodying my inventioninstalled on a car. F 2 shows a detail of one of the stops in theroadway forming part of my apparatus. I

In these drawings A is a portion of a rail road track; B B portions ofcar-trl'icks;

C'a compressed air tank commonly used in connection with brake and othermechauismv on cars, and D a station indicator in a car. On the cartrucks B B I mount arms E E in which I- pivot swinging levers a a eachprovided with a spring 6 to normally retain the levers e e in aperpendicular position just inside of one of the rails of the track, andin the road-hed adjacent to said.

rail I place a stop F preferably made to be of the truck Wheels passover it; a pre erable ty e of which stop F and its location relative yto the rail is clearly shown in Fig. 2. The object of lacing'the stop inthe path of the wheel ange and making it depressible is to presentaslittle obstruction to vehicles on the street surface as possible. Fromthe levers e e flexibleconnections e and lead to studs on opposite sidesof a Wheel G supposedly mounted on a car-body supported -by tli'e trucksB B, so that as the car moves in the. direction of the arrow a the leverwill engage the stop F and rotate the wheel G, while the lever c'-willpass over the stop without affecting it; and vice versa,-.

when thecar' is moving in the direction of the arrow at" then the lever6 will so engage the stop F as to rotate the wheel Gl' From the" wheel Ga belt g-,'preferably of sprocket-chain construction, extends to andaround a suitable pulley H onthe stem of an ordinary three-way valve notspecifically shown) mounted in a pipe. 0 leading fromf the air-tank G,to a cylinder I, so that when the valve is opened air will pass throughthe pipe 0 from the tank G into the c linder I and move thepiston 1against t e spiral spring P, so as to communicate the motion of thepiston I" through the rod i to one arm.

of a bell-crank lever J, the other arm ofwhich connects by means of arod with one arm of a second bell-crank lever'L, the other arm of whichis connected by means of a rod with a station indicator D, which isthereby actuated. For the purpose of allowing the spring I to move thepiston If back to its normal position ready to again operate, I

make exhaust openings 2"and i in the 01dinder I, the exhaust opening a"connecting with a small cylinder N in which there is apiston providedwithni racked bar n which inter-meshes with a segment of gear h on theshaft of the three-way valve in the pipe 0,

which when the head of the piston I passes the opening .71 in thecylinder I allows air to pass from the cylinder I into the smaller:cyl-.- inder N,-which operates to drive the-piston clearly obvious thatfurther description thereof is deemed unnecessary. Therefore hav ingshown and described my invention so as to enable others to construct andoperate the same,

a The combination of a station indicator ac-- tuating mechanism and avcar, comprising substantially, a car, -an actuating cylinder and piston,and a station indicator, means connecting said piston with the station'indihat I claim as new and desire to secure byLetters-Patent is:

from for closing said va1ve,-substantia1ly as 10 set forth.

In testimony whereof I affix my signature, in presence of two witnesses.
